Ast-ParentChild

Ast-Parent-Child is a CLI tool to generate the AST of a given JavaScript file, and then it will output a json file which has a parent-child relationship format for the AST rather than outputting a ordinary AST JSON format.

Ast-ParentChild uses AcornJS under the hood to generate the AST.

Usage

``bash
$ npm i ast-parentchild
$ ast-parentchild /path/to/javascript/file.js /output/path/of/file.json
`

Example

The following is the input JavaScript file sample.js.

`javascript
const example = "example";

`

The following is the output JSON file output.json.

`json
